Selected mixtures in 69 binary systems involving AlO, GaO, CrO, FeO, ScO, InO, YO, and the rare earth oxides were studied by X-ray diffraction techniques after heat treatment at various temperatures. A plot of the radii of the A cations versus the radii of B cations shows the regions of stability for the different structure types found for the double oxides of the trivalent cations. The following structure types were encountered: A, B, and C-type rare earth oxide; corundum, beta gallia; kappa alumina; garnet; perovskite; and several types which could not be definitely related to known structures. The majority of ABO compounds have the perovskite structure. Several phases, including (1-)FeO·AlO and (1-)FeO·GaO, appear to have structures similar to kappa alumina. Solid solution definitely occurs in many of the garnet type compounds which contain gallia. Based on the data collected in this survey, the subsolidus phase equilibria relationships of 79 binary systems were drawn.
通过X射线衍射技术研究了69个二元体系中的选定混合物，这些体系涉及AlO、GaO、CrO、FeO、ScO、InO、YO以及稀土氧化物，研究是在不同温度下进行热处理之后开展的。A阳离子半径与B阳离子半径的关系图显示了三价阳离子双氧化物中发现的不同结构类型的稳定区域。遇到了以下结构类型：A、B和C型稀土氧化物；刚玉、β-镓氧化物；κ-氧化铝；石榴石；钙钛矿；以及几种无法明确与已知结构相关的类型。大多数ABO化合物具有钙钛矿结构。包括(1-)FeO·AlO和(1-)FeO·GaO在内的几个相似乎具有与κ-氧化铝相似的结构。在许多含镓的石榴石型化合物中肯定会发生固溶体。基于本次调查收集的数据，绘制了79个二元体系的亚固相平衡关系。
